I have recently updated my computer system to Windows 7. Even though it is more user friendly than Windows XP I used to work with, I still had difficult time to move on. I am using CorelCAD and I wonder is it necessary for me to move to Windows 10? I know Microsoft stopped supporting 7 and now I am a little scared to get updates for my tools. What if the stop working? But if I move on to Windows 10 do I need to buy CorelCAD again? Forgive being gullible but I am not a very tech savy person. I have my tools I know and like but other than that, yikes!
